MEASURING THE INFLUENCE OF SPATIAL CONFIGURATION ON ACCESSIBILITY OF OPEN SPACE IN THE WANCHAI DISTRICT OF HONG KONG

摘要

Whilst Hong Kong is suffering from a limited supply of developable land in its major urban areas, some open spaces are frequently criticized as inconvenient for users, consequently leading to an ineffective use pattern. How to enhance the performance of open space is therefore a critical issue faced by city planners. As the conventional accessibility model, which is mainly described with respect to maximum walking distance or service radius, is inadequate to give an account of the issue, this paper accordingly indicates an alternative approach and seeks an explanation from the urban configuration and the way it conditions pedestrian movement pattern. Through investigating the relationship between urban configuration, pedestrian movement and accessibility and use of open spaces based on the Wanchai District of Hong Kong, which particularly epitomizes various urban grids that may have different consequences on the utilization of open space, this study aims to examine whether there is a consistent relationship existing in different spatial grids or whether the relationship varies from different layout patterns. It is hoped that the findings can be employed to improve the performance of open spaces in the urban areas of Hong Kong, in addition to other similar urban environment.
